Extended arm of excavator can effectively extend the working range of excavator and improve excavation efficiency in engineering construction. However, with the increase of difficulty, more attention should be paid to the prevention of hydraulic overheating phenomenon in operation to avoid major accidents after transforming equipment into extended arm of excavator. The following Xiaozhang will explain three measures to prevent the hydraulic overheating of the extended arm of excavator in the actual operation, hoping to help you in life.
Excavator Extended Arm
1. Oil quantity should not exceed the list.
When adding hydraulic oil to the excavator's elongated arm, the injection quantity must be controlled within the oil mark line, because after exceeding the standard, the excavator will generate a lot of heat during the steering process of the damper and transfer it to the hydraulic pump, which will cause the system to heat up, so the oil in the damper should be discharged to the standard oil level.
2. Do a good job of routine inspection
In order to prevent the occurrence of hydraulic overheating in the elongated arm of excavator, it is necessary to do a good job of routine inspection of the hydraulic system condition. Every day, it is necessary to check whether there is leakage at the connection points, whether there is enough oil in the tank, whether the working temperature of the pump is normal, whether the oil filter is blocked, and so on. If we can check and consult these places, we can effectively prevent the hydraulic oil temperature from being too high. In addition, check the relief valve of the excavator's elongated arm to ensure that the adjustment pressure, spring and spool seat are normal.
3. Remove and wash snake-shaped pipes regularly蛇形管和多管冷却器是液压系统的冷却保护装置，所以为了避免挖掘机加长臂出现液压过热，应该定期使用氢氧化钠及碳酸钠清洗，将油污清洗干净后再用温水清洗，如果能再放在按一定比例稀释后的硫酸溶液中浸泡四十分钟，那么蛇形管和多管冷却器的清洗效果会更好。
Serpentine tube and multi-tube cooler are cooling protection devices of hydraulic system, so in order to avoid hydraulic overheating of excavator's elongated arm, it is necessary to use sodium hydroxide and sodium carbonate regularly to clean the oil contamination and then use warm water to clean it. If the serpentine tube and multi-tube cooler can be immersed in sulfuric acid solution diluted in a certain proportion for 40 minutes, then the cleaning effect of the serpentine tube and multi-tube cooler is good. It will be better.
Hydraulic system overheating is a serious hidden danger to the excavator's elongated arm. Therefore, in order to ensure the high-quality elongated arm equipment, we should not only know which manufacturer of the excavator's elongated arm is good, but also do a good job of hydraulic overheating protection in use, so as to ensure that there is no hidden danger in the process of using the excavator's elongated arm.
